RADIATOR ATTACHMENT.

Application filed April 3, 1923. No. $29,730.

To all whom it may concern:

Be it known that I, ELLA PARKE, a citizen of the United States, residing at Kewanee, county of Henry, State of Illinois, administratrix of the estate of JAMEs F. GREEN- .s'rnnn'r, late a citizen of the United States, and a resident of Kewanee, in the county of Henry and State of Illinois, deceased (as by reference to theduly certified copy of letters of administration, hereto annexed, will more fully appear), do hereby declare ed a new and useful Improvement in Radiator Attachments, of which the following is a specification.

This invention has reference to radiator attachments, and its object is to provide an attachment for steam or hot water heating radiators, whereby a circulation of warmed fresh air may be caused.

The invention comprises a casing attachable to the basic portion of a radiator, of standard construction, in elevated relation to the floor upon which the radiator is mounted, and the casing is provided with removable portions of drawer-like construe tion in underriding relation to the casing and arranged to register with fresh air openings in the wall of the room in which the radiator is located. The arrangement is such that the attachment may be applied to the radiator without any change whatever in the latter and fresh air may be conducted into the room in a rising direction through the radiator so as to become efiec-tively warmed and thereby distributed. The attachment is also susceptible of adjustment to out 0d the inflow of fresh air, either in whole or in part, whereupon the radiator will act in a manner similar to ordinary radiators without attachments like those provided by the invention.

The radiator attachment has the advantage of being of a particularly sanitary nature, permitting access to various parts for cleansing and dismantling in whole or in part, and for adapting the attachment to larger or smaller radiators or to restrictions or extensions of the fresh air directing feature.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings Figure 1 is an elevation of a radiator with the attachment applied, the upper portion of the radiator being broken away.

Figure 2 is a section on the line 2-2 of Figure 1, with the section continued through the wall of a building to show fresh air ducts 7 leading thereinto.

Figure 3 is a plan view of the casing or box structure.

Figure 4 is a section on the line 4-4 of Fig.3.

Figure 5 is a section similar to Fig. 2 but taken on a line corresponding to the line 55 of Fig. 3.

Figure 6 is a perspective view of a portion of the casing as seen toward one inside corner.

Figure 7 is a perspective view of a latch member forming part of the drawer structure.

Figure 8 is a detail view showing the means for actuating the rear damper, the latter being shown 1n closed position.

Figure 9 is a view similar to Fig. 8, but showing the rear damper in open position.

Figure 10 is a section on the line 10-10 of Fig. 6.

Referring to the drawings, there is shown in Figures 1, 2 and 5 a radiator l which may be taken as indicative of an ordinary steam or hot water radiator, provided with the customary legs 2 by means of which the base of the radiator is elevated a short distance above the floor upon which the radiator is supported, such floor being indicated at 3. It is customary to locate radiators for househeating purposes close to the wall and usually close to the outer wall of the building and such wall is indicated at 4.

The radiator 1 is shown as of the sectional cast type with the sections provided with hubs 5 at the base portions by means of which the sections are connected together by nipples or otherwise. The legs 2 very in height in difierent radiators but such differences in height do not afiect the invention which is equally applicable to radiators which are hung on the wall of the room by hooks or otherwise.

The attachment includes a box or casing 6 extended lengthwise of the radiator and including one or more sections composed of front and back plates 7 and 8 respectively, intended to be placed in front of and to the rear of the radiator, and end members 9 to which may be added an intermediate member 10. Each of the members 9 and 10 may be thicker or of heavier gage material than the front and back members 7 and 8 and may be in the form of a casting, while the front and back members may be of sheet metal, these, however, being features of manufacture. Each member 9 and 10 has the bottom edge formed into a series of steps 11, 12 and 13 with the bottom edges of the steps 11 and 12 formed with undercut guides 14. At a point about midway of the length of each member 9 and 10 there is a cutaway portion 15 so arranged as to receive one of the hubs 5 on a corresponding one of the sections of the radiator 1, so that the end or intermediate member 9 or 10, as the case may be, rests upon and is supported by the hub of the radiator with the steps 11, 12

and 13 at respectively lower levels than the.

top of the hub.

The front and rear plates 7 and 8 are made fast to the end members 9 by means of pairs of lugs 16, formed on the end and intermediate members, and bolts 17 extending between the lugs and traversing the front and rear plates 7 and 8. The intermediate member 10 differs from the end members 9 in that it has pairs of lugs 16 on opposite faces so as to engage abutting front and rear plates 7 and 8.

While the invention may be so constructed that the front and rear plates may extend the full length of the radiator, it is preferred to make the casing or box 6 of a plurality of parts lengthwise of the box, whereby relatively short boxes may be applied to correspondingly short radiators or to include but a portion of the length of the radiator.

F or long radiators two or more of the boxes may be employed, in which case the intermediate members 10 are included, this, in some respects, simplifying the structure and permitting a wider application of the invention without necessitating a corresponding increase in patterns.

The members 9 and 10 being of stepped construction, stop at the front at about the level of the hubs of the radiator sections while the rear ends of the members 9 and maaeee For manufacturing reasons the front and rear plates 7 and 8 may be practically identical but because of the greater drop of the rear portions of the members 9 and 10, the rear plates 8 have continuations 18 in the form of plates extending to the bottom of the step 13 where each continuation is formed with an inturned ledge 19. Where the plates 8 and 18 join, the upper edge of the plate 18 is formed or provided with a step 19 into which the lower edge 20 of the plate 8 extends, the lower edge 20 being outset for a short distance, thereby forming a strengthening bead at the bottomof the plate 8. Similarly the lower edge of the front plate 7 has an outstanding bead 21 and the members 9 and 10 are shaped, as shown at 22, to correspond to the bead formation at the bottoms of the plates 7 and 8. Furthermore, the inner faces of the lower portions of the plates 7 and 8 are provided with lugs 23 entering corresponding notches 24 in the end edges of the members 9 and 10. Such construction permits the rigid joinder of the end and intermediate members 9 and 10 and the front and rear plates 7 and 8 with single bolts 17 where engaging. Similarly the plates 18 have lugs 23 and the step portion 13 of each member 9 and 10 has a notch 24; for the same purpose.

In the particular construction shown, the casing or box is composed of two main members divided intermediately and joined by the intermediate member 10 but it will be understood that where shorter structures are desired the intermediate member 10 is omitted and but one front plate 7 and rear plate 8 with the drop continuation 18 are used, this being permitted by the sectional construction of the device.

Each drop continuation-18, where two are used, is provided near its lower edge with an opening 25 elongated to an appropriate extent and provided on the side of the plate 18 remote from the radiator with a tubular extension 26 corresponding in outline to the shape of the opening 25. The tubular extension 26 is telescoped into a similarly shaped duct 27 extending into the room from the wall 4, which latter is pierced by an opening 28 of like shape to the duct, the opening communicating with the atmosphere outside of the wall. The duct, which may be expanded as it extends into the room, is provided exterior to the wall 4 with a border frame 29 in which there is lodged another frame 30 carrying a deflector plate 31 set at an upward inclination so that air may enter the duct, while rain or the like which may also enter the duct is directed toward the outside of the building. The duct is further protected by a screen 32 and an external frame 33 holding the several parts in place against accidental escape. lit will 1,542,869 ii-l m understood that the duct structure described with more or less detail is susceptible of changein various ways as may be desired.

The lower end of the box or casing 6 is closed by a drawer structure 34 of similar construction to the casing in that it is made sectional soas to be adaptable to long orshort radiators or long or short portions of radiators. Moreover, the drawer structure is so arranged that it may be introduced into or withdrawn from the lower portion of the casing in order to permit cleansing of the latter, and when introduced forms aclosure for the bottom of the casing, supplying those parts of the bottom of the casing not provided by the easing itself.

The drawer structure comprises end members 35 similar in some respects to the end members 9,- and also includes an intermediate or partition member 36 similar in general respects to the intermediate member 10 of the box or casing structure. The

drawer structure likewise is provided at the front of the end members 35 and partition 36 with pairs of lugs 37 by means of which a front plate 38 is secured to the end members. and partition by bolts 39. The end and intermediate members of the drawer structure have ledges 40 for receiving and carrying metal sheets 41 constituting the bottoms of the drawers, being also supported by the ledges 19 of the plates 18 when the drawers are in the inserted position.

The fronts 38 of the drawer structure have inturned flanges or ledges 42 upon which the front edges of the bottoms 41 rest. 1 The top edges of the fronts 38 have outstanding shoulders or step portions 43 similar to the step 19 and these steps 43 receive the beads 21 of the front plates 7 when the against the door or drawers-are pushed in to their limit. When so pushed in the bottom plates 41 engage over and are sustained at their inner edges by the ledges 19. The plates 41 are held the ledges or flanges 40 by a rod 44 traversing the side members 35 and the intermediate member 36 when present, said rod being secured in place by nuts 45 which may be applied to it outsideof the members 35. The end members 35 and intermediate partition member 36 are provided near their lower outer corners with sockets 46 to receive pintles 47 of dampers or closures 48 for laterally elongated openings 49 in the front plates 36. The openings 25 in the plates 18 are similarly rovided with doors or dampers 50 carried y pintles '51 engaging in sockets 52 in the end members 9 or intermediate member 10, or both as the case may be. The door or damper 50 is made to open toward the interior of the drawer and damper 47 is also made to open toward the interior of the drawer, the arrangement being such thatwith the two doors or dampers connected, the front damper may be made to close the passage controlled by it and at the same time cause the rear damper to open, or the front damper may be opened and by its movement close the rear damper.

In order to permit this operation of the rear damper through the medium of the front damper, which is the only one easily accessible, and also to permit the easy removal of the drawer structure for the purpose of cleaning, the front and rear dampers are connected by a link 53 of special con struction shown separately in Fig. 7. Lengthwise the link is bent at a slight angle at or near the mid-point and at the point of bending the outer edge of the link is provided with a projection or shoulder 54.

At one end on the edge remote from the" shoulder, the link is formed with a projection 55 having one edge 56 rounded, the projection being in the form of a tooth. At the same end and beyond the tooth 55, the link is formed into a hook 57 shaped to project through a slot 58 in an inset portion 59 formed in the damper or door 48. On opposite sides of the slot 58 are lugs 60 arranged to embrace the tooth or projection 55 when the hook 57 is projected through the slot 58 and engages over that portion of the damper immediately beneath the slot 58. The length of the slot is sufiicient to permit the insertion or removal of the hook by moving the other end of the link downwardly before the device is assembled, but after assembling this is prevented by the floor 41.

At the other end of the link 53 there is formed a tooth or projection 61 similar to but smaller than the tooth 55 and having an outer rounded edge 62 beyond which there is formed an upturned tooth 63 with a rounded bottom edge 64 continued under the tooth 61 and terminating in an abrupt shoulder 65. The tooth 63 is adapted to project through a slot 66 in a boss 67 pressed rearwardly in the door or damper 50. The boss 67 is formed with a ledge 68 in the nature of a stop catch designed to ultimately engage the shoulder in which case the tooth 63 is extended through the slot 66 and engages behind that part of the boss 67 defining the upper end of the slot 66 When the door'or damper 48 is swung rearwardly or inwardly to open position, the inset portion 59 engages the lu 60 and moves the link 53 rearwardly. T is causes the rounded side of the tooth 61 to, engage the inner face of the boss 67 and swing the damper 50 to the closed position shown in Fig. 8. When the damper 48 is again closed, the link 53 is drawn forwardly, the shoulder on the tooth 63 engaging the upper edge of IOU the slot 66 to swing the damper 5O inwardly to open position as shown in Fig. 5. These movements are permitted by the peculiar shape of the link 53 Without the necessity of any keepers or other fastening devices for holding the link in position.

It is also to be noted from Fig. 9, that when the link 53 is drawn outwardly, the latter part of the opening movement of the damper is effected by gravity and the inclined bottom edge 64 of the tooth 63 permits the tooth to drop low enough to ride beneath the upper edge of the slot 66. When the damper 48 is closed, therefore, and the damper 50 is open, the entire drawer structure together with the links 53 may be re moved as an entirety, permitting free access to the interior of the attachment for cleaning the same, and may be just as readily slid back into operative position, the pointed 1 ends of the tooth entering the slot 66 until the forward curved edge of the tooth 61 engages the damper 50 in a manner to raise the same.

The end members 35 and intermediate member 36 of the drawer, when such intermediate member is used, are each provided with stepped portions corresponding to the steps 11 and 12 of the end members 9, and these stepped portions are formed with grooves 69 to receive the tongues 14, where by the drawer structure may be moved under and sustained by the casing structure with the drawer structure below the radiator, thereby closing the bottom of the box or casing and constituting the closure therefor.

In order to prevent the dampers 48 and 50 from opening beyond a certain extent, a pintle 51 of the door 50 carries a pin 70 having in its path a fixed pin 71 engaged by the pin 7 0 when the door has'opened to the desired extent.

The radiator attachment may be applied to or removed from the radiator without any change whatsoever in the radiator and without any fitting. Moreover, the radiator attachment is susceptible of extension or retraction to fita large or a small radiator or to provide for the inclusion of a greater or smaller number of radiator sections, whereby a portion only of the radiator may be included in the attachment, if such be desirable.

The arrangement is such that when the front door or damper is open, fresh air from the exterior of the buildin is shut ofl', and when the front door or amper is closed, fresh air is admitted to a point beneath the radiator to rise through the latter and be come heated. Where the attachment includes two or more sections, one section may be utilized and the other or others cut off as occasion may demand.

The attachment is'susceptible of manufacturein a manner requiring but one set of patterns for the production of the attachment in any length desired, the extension of length being produced by the mere expedient of adding sections or units all of like construction with the exception of the intermediate partition or partitions, the other parts all being the same whether the attachment be made up of a single unit or a multiple of single units.
